Production & Heritage

Diamond Creek Vineyards, founded in 1968 by Al Brounstein, pioneered the concept of single-vineyard, terroir-driven Cabernet Sauvignon in Napa Valley. The Red Rock Terrace vineyard spans seven acres of steep, north-facing slopes composed of red-tinted clay soil with significant iron deposits — conditions that limit sun exposure and yield wines of distinctive structure and aromatic complexity. For the 2018 vintage, hand-sorted berries underwent a four-to-five-day cold soak followed by seven to nine days of fermentation, then aged for 21 months in 100% new French oak barriques. The blend is 78% Cabernet Sauvignon, 13% Merlot, 4.5% Malbec, and 4.5% Petit Verdot, with only 599 cases produced.

Tasting Notes

Aroma: Deep garnet-purple in the glass, the nose opens with exuberant cassis and plum preserves before shifting toward cedar chest and pencil lead. Underneath, layers of black truffle, damp soil, and unsmoked cigar leaf reveal the iron-rich terroir's fingerprint.

Taste: The entry is medium to full-bodied, bursting with concentrated blackberry and dark cherry fruit. The mid-palate builds with crushed stone minerality and subtle savory inflections — black currant, dried herb, and a streak of mint — all supported by plush, velvety tannins that carry notable freshness rather than weight.

Finish: Long and fragrant, trailing off on earthy notes of damp soil and violets with a persistent mineral undertone. The tannin structure resolves smoothly, leaving a sense of contrasting brightness and composure that invites the next sip.

How to Drink Red Rock Terrace 2018

This wine is best served neat in a large-bowled Bordeaux glass at 60–65°F; decanting for 60–90 minutes allows the layered aromatics to fully unfold. Given its structure and complexity, it rewards patient, contemplative drinking and pairs exceptionally with food rather than cocktail use.

Best For

• Anchoring a serious Napa Cabernet vertical tasting alongside other Diamond Creek vineyard designates
• Gifting a wine collector who values terroir-driven, single-vineyard bottlings
• Cellaring for long-term aging — the tannin structure and acidity suggest a 15–25 year drinking window
• Pairing with a celebratory prime rib or special-occasion dinner

Frequently Asked Questions

What does Red Rock Terrace 2018 taste like? It delivers concentrated cassis, blackberry, and plum preserves layered with earthy black truffle, pencil lead, and crushed stone minerality. The tannins are plush and velvety, finishing long with fragrant soil and violet notes.

How does Red Rock Terrace compare to Diamond Creek Gravelly Meadow? Both are single-vineyard Cabernets from the same estate on Diamond Mountain, but Red Rock Terrace's iron-rich clay and northern exposure produce a more structured, mineral-driven wine, while Gravelly Meadow's well-drained alluvial soils tend to yield a rounder, more immediately fruit-forward profile. The 2018 Red Rock Terrace scored 98 points from Wine Advocate compared to Gravelly Meadow's typically high but distinct critical reception.

Is Red Rock Terrace 2018 good for cellaring? Yes — the wine's firm tannic backbone, bright acidity, and concentrated fruit suggest it will develop beautifully over 15 to 25 years, though it already shows generous complexity with proper decanting.

Where is Red Rock Terrace made? It is produced by Diamond Creek Vineyards in the Diamond Mountain District AVA, a high-elevation sub-appellation in the western hills of Napa Valley, California. The Red Rock Terrace vineyard sits on a steep, north-facing hillside at the estate.

What foods pair well with Red Rock Terrace 2018? Grilled lamb chops with rosemary complement its herbal undertones; dry-aged ribeye steak matches the wine's tannic weight; braised short ribs echo its earthy depth; aged Comté or Gruyère cheese highlights the savory minerality; and mushroom risotto with black truffle mirrors the nose beautifully.

What sizes does Red Rock Terrace come in? The standard release is a 750ml bottle, consistent with Diamond Creek's single-vineyard offerings.

Is Red Rock Terrace 2018 worth the price? Red Rock Terrace positions firmly in the ultra-premium tier of Napa Valley Cabernet, and the 2018 vintage — with its 98-point Wine Advocate score and a production of just 599 cases — represents one of the strongest recent expressions from this vineyard, offering compelling value relative to comparably scored Napa cult wines.

Why Red Rock Terrace 2018?

The 98-point score from Lisa Perrotti-Brown at The Wine Advocate signals this as a benchmark vintage for the Red Rock Terrace vineyard. What separates this wine from other elite Napa Cabernets is its seven-acre source of iron-rich, oxidized red clay on a steep north-facing grade — a microsite that simply does not exist elsewhere in the valley. With only 599 cases produced and a blend refined through 21 months of new French oak élevage, the 2018 captures the rare intersection of power, mineral precision, and aging potential that has defined Diamond Creek's reputation since 1968.
